BULKHEAD AND JETTY CONSTRUCTION.

Specification of Letters Patent.

Patented Sept. l, 1908.

Application led December 10, 1906. Serial No. 347,062.

To all whom it may concern:

Be it known that we, JESSE A. HowLAND, a resident of Sea` Bright, in thecounty of Monmouth and State of New Jersey, and NILLIAM H. DE NYSE, aresident of Long Branch, in the county of Monmouth and State of NeTJersey, both citizens of the United States, have invented a new andImproved Bulkhead and Jetty Construction, of which the following is afull, clear, and exact description.

The invention relates to hydraulic engineering, and its object is toprovide a new and improved bulk-head or ajetty construction, moreespecially designed for use along the coast in harbors, rivers and otherwater ways and arranged to form a lasting protection against the ravagesof the sea, teredos and other destructive causes.

The invention consists of novel features and parts and combinations ofthe same, which will be more fully described hereinafter and thenpointed out in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure l is a plan view of the improvement in the form of a jetty, partsbeing broken out g Fig. 2 is a face view of the same, parts being brokenout, Fig. 3 is a transverse section of the saine, and Fig. 4 is a likeview of the improvement in the form of a bulk-head.

On a Suitable support 0r like structure A driven into the bed of thewater way is se cured a driven sheet planking B, and a backing C ofconcrete is arranged at the rear of the planking B and embeds 'the upperportion of the support A. Now for a jetty the sheet planking B isarranged on both sides of the support A as well as on the end thereof,as will be readily understood by reference to Figs. 1 and 2, but forbulk-heads such as illustrated in Fig. 4, it is only necessary to usethe planking B on the front face of the support A.

The support A shown in Figs. 1, 2 and 3 consists of spaced pairs ofpiles A the piles in each pair abutting at their upper ends, to thendiverge in a downward direction, and to the outer sides of the pairs ofpiles A are secured by bolts D, D the upper and lower stringers A2, A3,thus forming a strong supporting structure for the planking B. The

driven planking B consists of concrete reinforced tongued and groovedplanks, such as more fully Shown and described in the application forLetters Patent, Serial No. 347 ,O61 filed under even date herewith. Theplanks are driven down into the bed of the water way along the stringersA3, A3 as guideways, and as the planks interlock with each other bytheir tongues and grooves (see Fig. l), it is evident that a continuoussheet planking is produced and which extends a desired distance into thebed of the water way. The individual planks are secured by bolts E to helower stringers A3, and bolts E connect the upper ends of the planks onboth sides of the support A with each other, the said bolts E alsoextending through the upper portion of the concrete backing O.

Now in forming the jetty, the piles A are first driven into the bed ofthe water way, after which the stringers A3, A3 are secured in place bythe bolts D, D', and then the concrete planks are driven down into thebed of the water way along the stringers A3, A3 as guide ways, afterwhich the planks are bolted in place, as above described. Now thematerial of the bed of the water way extending between the plankings onopposite sides of the structure A is excavated, if necessary, to thedesired depth and the space is iilled with the concrete O which onsetting forms an exceedingly strong backing for the plankings B, at thesame time the concrete embeds the upper portion of the support A, thusrendering the entire structure exceedingly strong and durable, so as toreadily withstand the force of the waves. The planks at the end of thejetty are fastened in place by bolts E3 engaging the end pair of piles,as plainly indicated in Fig. l.

When building the bulk-head shown in Fig. 4, pairs of piles are driveninto the bed of the water way, each pair consisting of two piles A4, A3,of which the front pile A4 is pressed by the rear pile A5, and the twopiles are fastened together at their upper ends by a bolt E4. Thestringers A, A7, A8 are secured to the outward face of the front pilesA4, and to the stringers are secured the planks for forming the plankingB, and then the concrete backing C is placed in the rear of the plankingso as to embed the upper portion of the support A. As shown in Fig. 4,the concrete backing C is reinforced from the top to the bottom by asuitable metallic reinforcing material F such as wire netting, and thebacking is preferably extended above the top of the planking B as wellas the support A, so as to form a coping for the structure, the copinghaving a tendency to deflect the water back into the water way.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent:

l. A bulk-head, etty or like structure comprising a support formed of aplurality of spaced and connected piles driven into the bed of the waterway, a driven concrete sheet planking held on the said support, and abacking for the said sheet planking and cmbedding the upper portion ofthe said suport.

2. A bulk-head, jetty or like structure comprising a support -formed o'lspaced pairs of piles driven into thc bed of the Water way, the piles ofeach pair oi piles diverging downwardly, and stringers connecting thepairs of piles, driven interlocked concrete planks attached to the saidsupport, and a concrete backing i'or the said planks and embedding theupper portion of the said suport.

3. A bulk-head, jetty or like structure comprising a support, sheetplanking-s on opposite sides of the said support, and a backing ofconcrete for the said sheet plankings and embedding the upper portion ofthesaid support.

. comprising a support 'formed of a plurality of pairs of pilesconnected together, the piles of each pair of piles being securedtogether and having their lower ends diverging, concrete plankingsecured to the support, and a backing of concrete 'for the said plankingand embedding the upper portion of the piles.

5. A bulk-head, jetty or like structure comprising a support, and sheetplankings on opposite sides of the said support and formed ofinterlocked concrete planks, driven down on the said support asguideways and iirmly secured thereto.

6. A bulk-head, jetty or like structure comprising a support, sheetplankings on opposite sides of the said support and 'formed ofinter-locked concrete planks driven down on the said support asguideways and iirmly secured thereto, and a concrete iilling between thesaid plankin gs and embedding the upper portion of the said support.

7. A bulk-head, jetty or like structure comprising a support formed ofspaced pairs of piles driven into the bed of the water way, the piles ineach pair of piles diverging in a downward direction, and stringerssecured to the outside of the pairs of piles, and concrete planks drivendown into the bed of the water way along the said stringers as0ruideways, the said planks being of reiniorced concrete and interloekedto form an uninterrupted sheet of planking on each side oi' the saidsupport.

8. A bulk-head, jetty or like structure comprising a support formed ofspaced pairs of piles driven into the bed of the water way, the piles ineach pair of piles diverging in a downward direction, and stringerssecured to the outside of the pairs of piles, concrete planks drivendown into the bed of the water way along the said stringers asguideways, the said planks being of reinforced concrete and interlockedto 'form an uninterrupted sheet of planking on each side of the saidsupport, and concrete interlocked planks around the end of the supportand interlocked with the sheet plankings at the sides of the supports.

9. A bulk-head, jetty or like structure, comprising a support 'formed ofspaced pairs of piles driven into the bed of the water way, the piles ineach pair of piles diverging in a downward direction, and stringerssecured to the said outside of the pairs of piles, concrete planksdriven down into the bed of the water way along the said stringers asguideways, the said planks being of reiniorced concrete and interlockedto form an uninterrupted sheet of planking on each side of the saidsupport, and a backing of concrete between the said plankings andembedding the upper portion of the said support. j

10. A bulk-head, jetty or like structure comprising a support, a drivenconcrete sheet planking held on the said support, and a backing -for thesaid sheet planking and embedding the upper portion of the said support,the said planking and the said backing extending upward beyond the topof the said support.v
